OS Security and Endpoint Capabilities

Imagine an enterprise network as a sprawling, decentralized metropolis. Historically, security architects built massive perimeter walls—firewalls and gateways—expecting them to keep adversaries out.

A traditional network-based firewall acting as a perimeter checkpoint, a model that is increasingly insufficient for modern decentralized enterprise access.

Modern infrastructure, however, operates on a different reality. The perimeter has dissolved. Employees access sensitive data from coffee shops, branch offices, and home networks, meaning the modern battlefield is the endpoint itself and the communication protocols binding these disparate nodes together.

Securing this environment requires shifting our focus from the network perimeter to the operating systems, the endpoints, and the primary vector of business communication: email.
